In case you are looking for a way to learn/practice with Hog 4 and Capture, there is now a demo pack available at the Capture website. This includes presentation files for Mac and PC (which are free to use Capture viz files - no license required), a Capture file to play with in the Capture lighting design software itself, and a Hog 4 base file if you want to jump in. There is also a guide for connecting Hog 4 to Capture (nicked from the user manual). Happy Hogging!
